COUNTINIG'DEVICE..

.WfiLLIAM v`HUCKS, Jr., engineers, subjects. of

the King oflGrreat Britain andIreland, residing at James;` street, Camden ATown, in the, county ofl London, England,have invented new -and useful Improvements Counting Devices, ofwhich the following` is va'speciicacasing, or chamber into which the aerated aerated 1s attached, we fix a body A, havin corder.

tached to thepart Av by screwsa.

liquid or the aerating gas passes in the successive operations of drawing off or aerating is provided with a movable part which isact cdupon by the pressure of the gas and which by itsmovement is caused by anyv suitable.y v

connection or gear to loperate a counter or re- ()ur inventionl is applicable, for example, to apparatus of the character described in the specification of Letters' Patent N O.` 15,435, AAD. 1903, granted to SodaStream Limited and one of us-namely, William Iiucks, Jia-and the following is a description-(with reference to the section shown in 'the `accompaDying drawing) of a rconvenient construction ofthe ldevicevaccordin to our. present invention as applied to suc appa. rat-us, from ywhich its general application will also beunderstood; but we do not limit Ourselves to this` particular construction.` l

In an opening in the casing or chamber, (part of which is 'indicated at 1,) to which the bottle or the like containing the liquid to be ya passage a in it and containin the heady b o a piston or valve B, on whic is secured a piece b2, acting as .a guide in apart A2, at- The piston B isA pressed forward by a spring C,bear ing at one end on thebase of t the partAand at theothcr end on the piece b2, so that the face oi' the piston-head b normallyv bears upon the seat 'surrounding the spcifiation of Letters Patent. Appimiion iiiea August 3,1905. serai No. 273,303.

chamber 1.1 The rear part' or rod of the pis- D ,between-,the rear of the piston-head bxand -theaforesaid part A2 to prevent passage of gas ltojjthe interior ofthe said part A2, lthe outer edg'e'of the said'diaphraginbeingpinched bel :tweenthe parts A A2 and fits yinner ledge being jpinched between therear of the piston-head b `the v`piece ,b21 upon the piston B. vThe .said i yrear part or -rod of the piston toward its outer end fis provided with a notch b3 for acting anda washer'd, pressed `forward by screwing upon apin f on a lever F, which actuates a "counter or ,recorder which is secured to the said body, (the casing ofl this counter or rethus l operatedl once for each in consequence of thepressure of gas in the 'ton B has, preferably, an elastic diaphragm l l7o corder is shown at .E,) the said counter or ref.

vcorder lbein A v 4'a'e'rzat'ionof t e successive quantities of liquid aforesaid casingor chamber 1 moving the piston B' outward, the spring C returning the 'said piston to its closed position when the pressure .ofgas is relieved.

We claim as our inventioni 1. In combination with an'apparatus for .aerating liquids and the like, means for actuating a counter to denote the number o f operations effected, 'said means comprising a chamber with. a connecting-passage into vwhich the aeratinggas passes in =drawing olf, f

a piston in said chamber acted on bythe pressure of the gas, an elastic ydiaphragm cham er, and a counter actuated by the reciprocations f the piston. j

ating a counter to denote the number of operations effected,` said means comprising a yseparating said piston from the connecting `passa e to prevent the gas from entering the chamber with a connecting passage into. which the aerating-gas passes in drawing ofi",

a piston in said chamber acted on by the v pressure/of the gas', an elastic diaphragm separating said piston from; the connecting-pasi sage, a spring for retirning the'pistonto its IOO closed positionwhen the pressure of the gas v *n is relieved, anda counter at the end of .the-

piston-rod and'actuated thereby.

In testimony whereof We have signed this vspecification in the resence of two Witnesses.
